What is cost per day (CPD)?

Cost Per Day (CPD) is a metric used to measure the average cost incurred per day for a specific activity, project, or campaign. It is most commonly used to calculate the daily spend on advertising campaigns, subscription services, or project costs. By calculating your CPD, you can efficiently plan and manage your budget for the given project.

Understanding the cost per day result

The ideal CPD will depend on various factors such as your targets and the project/activity for which you are measuring the CPD:

  • A low CPD indicates that the project is running efficiently, with minimal daily expenses.
  • A high CPD suggests that you are incurring relatively high daily costs and that you might need to optimize your efforts.

When to calculate cost per day

CPD should be calculated whenever you want to understand the average daily cost of an ongoing activity or campaign. CPD should be calculated in the following key situations:

  • During financial planning or budgeting to estimate daily expenses
  • For evaluating the daily costs of running a marketing campaign, project, or operation
  • To compare costs over different time periods or across multiple projects
  • When analyzing the financial performance of subscription services, SaaS models, or other recurring expenses
  • To identify trends and patterns in spending that may require cost optimization

How to calculate Cost per day with example

Let’s say you spent $15,000 on an ad campaign that lasted 30 days. You can calculate CPD as follows:

CPD = Total Cost​/Number of Days

CPD = 15,000/30 = 500

In this example, your CPD is $500, which indicates that you spent $500 on average per day on the project.

How to improve your cost per day

You can improve your CPD by using the following strategies:

  • Optimize your ad targeting to reach the most relevant audience.
  • Adjust your bidding strategy to control costs effectively.
  • Use A/B testing to identify the most cost-efficient ad formats.
  • Refine your ad content to improve click-through rates.
